3.11.5 Code Objects 
</h2>
<a id='l2h-324' xml:id='l2h-324'></a>
<p>
Code objects are used by the implementation to represent
``pseudo-compiled'' executable Python code such as a function body.
They differ from function objects because they don't contain a
reference to their global execution environment.  Code objects are
returned by the built-in <tt class="function">compile()</tt> function and can be
extracted from function objects through their <tt class="member">func_code</tt>
attribute.
<a id='l2h-325' xml:id='l2h-325'></a><a id='l2h-327' xml:id='l2h-327'></a>
<p>
A code object can be executed or evaluated by passing it (instead of a
source string) to the <tt class="keyword">exec</tt> statement or the built-in
<tt class="function">eval()</tt> function.
<a id='l2h-328' xml:id='l2h-328'></a><a id='l2h-329' xml:id='l2h-329'></a>
